Measurement method: when measuring, the left hand grasped the tail root of the fox (the tail root is 2cm from the hindquarters), and put the point in the zero scale position of the ruler. The right hand holds the earpiece, the thumb holds the lower part of the ear root, and straightens the fox skin. At the same time, the thumb is vertically aligned to the ruler, and the reading is the standard length of the fox skin.
